OK, you've found me. Insert standard disclaimers -- I've got a
full part-time day job, which leaves my dance card open
for part time consulting, training, and related gigs (resume) and this is just something I'm starting
out doing haphazardly, under construction and highly
subject to change, as an "evolving situation".

Freenode.net provides IRC services to numerous Free Software
projects as a non-profit organization. They're running a
fundraiser. Help if you can.

Who am I?

Programmer, systems/network administrator, freelance tech writer,
Free Software
advocate, and general technology wonk. I frequently post to
discussions on GNU/Linux; Debian; copyright, patent,
trademark, and licensing; data processing and analysis; online
rights and privacy issues; and related topics. I'm interested in and
work on collaborative discussion topics including email, Usenet,
weblogs, Wikis, spam, and filtering methods. I've designed,
deployed, documented, or contributed to several of these, with more
work in process.

I used to actively fight and track spam, and report spam
statistics. (It got better). Now mostly historical: I found that ASNs
(autonomous system numbers) and CIDRs are highly useful for
aggregating spam activity. This is covered in more depth in my
paper "CIDR House Rules" (PDF).

If you want to add an X-ASN header to your mail via a
procmail rule, I've created the following recipie, procmail-asn-header.
Bayesian classifiers such as SpamAssassin and other should pick this
up and start classifying ASNs by spamminess, automatically.
